Metropolitan Area Network (MAN)
Precisely speaking, the definition of a Metropolitan Area Network has less to do with geography and more about technical specifications that are outlined is the guidelines set by IEEE (Institute of Electrical and Electronics Engineers). (This is said as eye, triple E) You will visit this topic briefly later in the course, in the chapter on Networking Standards.
Academic precision aside, you can think of a MAN as a network for a campus-like cluster of buildings, or two or more buildings within a short distance of each other in a city, as illustrated below. Of the three types of networks, the MAN is the least common. Theyre found in situations where sites are too far apart to use LAN technology exclusively (since LAN technology has limits on the distance it can run), but close enough together that high-performance can be achieved in a more cost-effective way than with typical WAN technology. The longer network links connecting the sites in a MAN are called its backbone.
